March for the Null Hypothesis!

I saw this in a Facebook group for the March for Scienc

I am marching for the null hypothesis! At the root of hypothesis testing is the possibility "I am wrong." In this era of "feelings are fact" and "opinions are facts", this is so very important. Say anything you want about science, but there is something so powerful about testing against the possibility that what we thought made a difference, did not. Living peacefully in a gray world requires this kind of bravery.
